Patent attributes
A swingable mechanical structure installed to fitness equipment or bicycles includes a machine base, a swing mechanism, and an auxiliary bracket. The swing mechanism includes a rotating shaft, a tilt member, and a swing post. The rotating shaft of the swing mechanism is installed into an assembling slot of the rotating shaft. Both ends of the auxiliary bracket are assembled to the machine base and an end of the swing post. When the rotating shaft is rotated, the rotating shaft is rotated to an angle with the respect to the tilt member, so that the swing post may swing together with the tilt member sideway and rotated around the tilt member. One of the ends of the swing post is limited by the auxiliary bracket, so that the swing post can just swing sideway to produce a mechanical structure with a force input and output conversion.
